8.) See increased processing and stockpile area on Mining Plan (Exhibit D).
9.) Overburden and topsoil stockpiles shall be kept at a minimum by replacing onto mined out
previous units. Stockpiles for final reclamation shall be re-vegetated until final use.
10.) A minimum of 2 feet of overburden or crusher reject (fines) shall be placed on any shale
exposed by mining activity within 180 days to minimize and prevent selenium exposure.
The underlying Mancos Shale appears to be previously oxidized and weathered (See Soils
Report.
EXHIBIT E -Reclamation Plan
11.) Statement providing a three year guarantee on the re-vegetation has been removed and
replaced with "re-vegetation shall be firmly established as determined by inspection by
Division of Minerals and Geology personnel".
12.) Statement that "No topsoil will be saved so underlying soils will be conditioned" was
removed and replaced with "specific unit by unit handling of the overburden and topsoil".
Exhibit L cost estimate was revised to reflect handling of topsoil and overburden. Across
section will be added to show final reclamation surface.
13.) The existing high waterline of the pit before discharge is elevation 4816.15. A ten (10) year
24 hour storm event shall be entirely contained within Unit 1 and Unit 2 detention area and
will accumulate storm water ( cu. ft.) from elevation 4813 to elevation 4816.
14.) Unit designation has been revised for soils handling and reclamation activities on Exhibit E.
The seed mix has been changed to follow the approved BLM criteria and application rates
for arid re-vegetation (see enclosed.)
15.) Re-vegetation seeding shall be scheduled in the fall between Sept. 1 and Oct. 15.
EXHIBIT F -Reclamation Plan Map
16.) Reclamation Plan Map as been revised to reflect final reclamation appearance.
EXHIBIT G -Water Information

The existing operation consumes approximately 120,000 gallons of water annually for the
development, mining and crushing and screening of the construction materials. No water
usage is proposed for reclamation.
Response to Rule 6.4.7 (4)
The only source presently used or proposed is supplied 100% by Ute Water.
Response to Rule 6.4.7 (5)
Upland Gravel is not required to apply fora (NPDES) permit because no discharge of
storm water is proposed or has occurred from the site. If necessary, the applicant shall
apply fora (NPDES) permit.
